APPARATUS FOR WINDING PAPER CARDBOARD AND LIKE TUBES.

like Tubes, of which the following is a specification.

This invention relates to the production of hollow cylindrical bodies or tubes from paper, pulp-board or similar cellulosie or fiexiblematerial in the form of sheets, and has for its object to provide an improved machine for use in the production of suchbodies.

According to the present invention, the

machine comprises a feed roller, a mandrel supported above and somewhat behind the feed roller, guiding means adapted to be brought into coiiperation with the mandrel for causing the sheet to be guided over the surface of the mandrel remote from the feed roller and to be moved away therefrom for facilitating the removal of the completed tubular bodies from the mandrel, and means adapted to raise the mandrel from the feed roller when the guiding means is so moved awe Tlie guiding means employed may be a sheet of suitable material, for instance, metahbent-so as to form substantially a. half cylinder adapted to cover a portion of the peripheral surface of the mandrel. This semi-cylindrical cover may be hinged at one edge so as to be swung back, renderin the mandrel accessible for the removal 0 the tubular bod formed.

If desire at certain points in this cover, openings may be arranged through which the peripheries of jockey rollers mounted in suitable bearin s on the cover project so as to contact wit the sheet material and ress the same against the mandrel. These ockey rollers are, with advantage, arranged so as to make directcontact with the mandrel when the sheet material does notinter- Yiene between the mandrel and the rollers,

in order to set up sufiicient friction to cause the sheet material when fed between them and the mandrel to be drawn forward by friction; and to increase this frictional effect, these jockey rollers may be driven Specification of Letters Patent.

through suitable gearing at a somewhat greater Jeripheral speed than the mandrel itself. 11 order to achieve this end, a spur wheel of rather larger diameter than the mandrel may be provided on the mandrel spindle and pinions of somewhat less diam 'hinging to suitable members, that they .and

the jockey rollers may be moved away from the mandrel to permit the removal of the tubular bod 1 formed. 7

Between t e jockey rollers wires, bands, or strips of suitable material may be provided in order to assist further in guiding or leading the sheet material against the mandrel.

This guiding means may be a sheet of a suitable material curved so that the edge of thesheet of material, to be wound into a hollow cylindrical body when it contacts with the guiding surface, is guided around a portion of the periphery of the mandrel, in order that the said sheet of material may be operated upon by the guiding means adapted to be brought into cooperation with the mandrel for causing the sheet to be guided over the surface of the mandrel remote from the feed roller and to be moved away for facilitating the removal of the bearing at one end and at the other end in a bearing adapted to be raised and pivoted about a center so that the mandrel may be swung to one side for the pur ose of removin the-tubular bodies forme thereon.

Tn order that the invention may be clearly understood, reference may be had to the accompanying drawings in'which, by way of example, certain methods of carrying the invention into effect are illustrated.

Figure 1 represents in elevation a machine in accordance with the invention, viewed from the side of the mandrel opposite to that from which the sheet materialis fed.

Fig. 2 is an end elevation on an enlarged scale of the mandrel, rollers and uides of the machine shown in Fig. 1; whi e Fig. 3 is an elevation of a portion of the mandrel and its associated guiding means gewed in the direction of the arrow i.

*igs. 4 and 5 are respectively a cross-section and a fragmentary view in elevation of an alternative form of construction; while Figs. 6 and 7 are respectively a cross-secs tion and a fragmentary view in elevation of a further form of construction.

In the drawings, like parts are indicated by like reference letters.

Referring more particularly to Figs. 1, 2 and'3, 1 represents the stand on whlch the machine is su ported; 2 the mandrel mounted on a spindle 3 supported at one end in a slip bearin 4 and at the other end. in

the bearing 5 w ich is secured to a rod 6 arranged to slide in guides 7, 8 and 9, and bearing through the intermediary of a ball 10 on one end of the foot lever 11.

On the spindle 3 there is also mounted a spur wheel 12 of rather greater diameter t an the mandrel; this wheel gears with the pinion 13 (see Fig. 2) which is of somewhat smaller diameter than the feed roller 14 on thaspindle 15 on which a is mounted. This wh'ee also gears with a pinion 16 secured on a shaft 17,911 which a roller or a plu rality of disks or narrow-faced rollers 18 are mounted, and this pinion is of such diameter that. the peripheral speed oi this roller or theflisks or rollers is greater than the peripheral speed of themandrel. 1

Behind the feed roller, a guide roller 19 is arranged which, as shown in 1, is

ved at 20, in order to accommo te the ngers 21 formed on a plate 22 which is secured to the supportingstandard 23 forming art di or secured to the bed plate 24. These ngers, as showmextend in an upward direction' and act as fixed guides for the sheet material directing the same upwardly to ward the guiding, means adapted to be brought into coiiperationwith the mandrel and tobe moved'ayay for the purpose of facilitatin the removal. of .the cylindrical bodies ormed.

of which the, container is In the machine illustrated by Figs. 1, 2 and3, this guiding means is a semi-cylindrical body 25, hinged on, and secured by means of the member 26 to a suitable su port which also serves as a support for t e member 17 supporting the guide 27 fiapped to permit the tightening disks or re ers 18 to ear against the mandrel.

In the construction illustrated by Figs. 4 and 5, the semiylindrical bod 25 is cut away and bearings 28 are provi ed for supporting spindles 29 on which jockey rollers 30 are mounted.

In the construction shown in Figs. 6 and 7, the semi-cylindrical body 25 of the construction illustrated in Figs. 4 and 5 is dispensed with, the jockey rollers 30 being secured on spindles 29 mounted in bearings in yoke-pieces 31 which, as shown, are ar ranged to pivot about the center of the shaft on which the tightening di'sks or rollers 30 are secured, in order that they ma be swung aside to facilitate the removal 0 the cylindrical bodies formed on the mandrel.

The operation of the machine illustrated in Figs. 1, 2 and 3 is as follows The sheet of paper or other material having been provided with a coating of adhesive material for a portion of its length suflicient to insure the several la ers being secured together while the interior of the tubular body shall be free from adhesive, is passed between the feed roller 14 and the mandrel 2 which is rotated by a crank handle or other suitable means (not shown) and rotates through the intermediary of the gear wheel 12, and the pinion 13 the feed roller 14. The sheet of material thus fed forward will be guided By the guide roller 19 and the fingers 21 formed on the plate 22 in an.upward direction and will contact with the semi-cylindrical cover 25 whose lower edge is chamfered so as not to catch theedge of the advancing sheet of material.

The semi-cylindrical cover will cause the sheet to travel around the mandrel to the point where the disks 18 contact with the mandrel and these disks being driven through the intermedia of the pinion 16 from the spur wheel 2 at 'a somewhat greater lperipheral speed than is the mandrel, wi 1 cause the sheet of material to be drawn closely against the mandrel and will cause the edge of the sheet to contact with the guide 27 which will direct this ed between the mandrel and feed roller. llhen the sheet 'of material has been entirely woundabout the mandrel and the latter has been rotated several times to Meet the con so'lidation of the severe] la era of material mod, and the semilindrical cover h' been swung ever, the r 6 may be caused slide-in its ides 7, 8 and 9 to raise the ,beariiig 5 an with it the mandrel 2 which may, then bepivoted about the center line of the rod 6 in order that the tubular body may be removed from the mandrel.

As will be understood, any suitable means for raising and lowering the mandrel, rotating the same and raising the semi-cylindrical cover, may be made use of and, if desired, rotary cutters may be p1 vidcd for the purpose of dividing the sheetof material as i; enters between the feed roller and the mandrel so that a plurality of tubular bodies may be formed from a single sheet of material.

It may, however, be stated that it is considered preferable to drive one of the rollers on which the mandrel rests when lowered into position, namely the roller on the feed side of the mandrel, in which case the mandrel will be driven by friction from the feed roller.

Having now described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. A machine for forming hollow cylindrical bodies from .paper, pulp-board or similar oellulosic material in the form of sheets comprising a feed roller, a mandrel sup orted above and somewhat .behind said feed roller, guiding means adapted to guide the sheet material fed between the feed roller and the mandrel in contact with the mandrel and in an upward direction, guid ing means adapted to be brought into cooperation with the mandrel for causing the sheet to be guided over the surface of the mandrel remote from the feed roller and to be moved away therefrom and means 2. A machine as claimed in claim 1, in

which the guiding means is a sheet of suitable material curved so that the edge of the sheet of material to be wound into a hollow cylindrical body when it contacts with the guiding surface will be guided around a portion of the periphery of the mandrel in order that the said sheet of material may be operated upon by the guiding means adapted to be brought into cooperation with the mandrel for causing the sheet to be guided over the surface of thetmandrel remote from the feed roller and to be moved away for facilitating the removal of, the tubular bodies.

A machine as claimed in claim 1, in which on the same side of the center line of the mandrel as is the feed roller, a roller or a plurality of disks arranged on a common .shaft driven at a somewhat greater speed than the mandrel is provided for the purpose of causing the sheet material to be drawn tightly around the mandrel.

4. A machine as claimed in claim '1, in which the mandrel is journaled at one end in a bearing adapted to be pivoted about a center so that the mandrel may be swung to one side for the purpose of removing the tubular bodies.

In testimony whereof I have signed my name to this specification.
